MimeKit is an Open Source library for creating and parsing MIME, S/MIME and PGP messages on desktop and mobile platforms. It also supports parsing of Unix mbox files.

     Unlike any other .NET MIME parser, MimeKit's parser does not need to parse string input nor does it use a TextReader. Instead, it parses raw byte streams, thus allowing it to better support undeclared 8bit text in headers as well as message bodies. It also means that MimeKit's parser is significantly faster than other .NET MIME parsers (more than 25x faster than OpenPOP.NET and over 100x faster than AE.Net.Mail and MailSystem.NET).

     MimeKit's parser also uses a real tokenizer when parsing the headers rather than regex or string.Split() like most other .NET MIME parsers. This means that MimeKit is much more RFC-compliant than any other .NET MIME parser out there, including the commercial implementations.

     In addition to having a far superior parser implementation, MimeKit's object tree is not a derivative of System.Net.Mail objects and thus does not suffer from System.Net.Mail's massive limitations or bugs.

* Fixed the MimeEntity.ContentId setter to use ParseUtils.TryParseMsgId() instead of MailboxAddress.TryParse() so that it is more lenient in what it accepts. (issue #542)
* Added an HtmlTokenizer.IgnoreTruncatedTags property which is useful when working with truncated HTML.
* Optimized the heck out of HtmlEntityDecoder.
* Added a TextPart.Format property for a quick way to determine the type of text it contains.
* Added text/plain and text/html preview/snippet generators (PlainTextPreviewer and HtmlTextPreviewer, respectively). This is part of a larger improvement to MailKit's text preview feature for IMAP. (MailKit issue #1001)
* Fixed SqlCertificateDatabase to accept null SubjectKeyIdentifiers.
* Changed Header.FormatRawValue() to be protected virtual and added Header.SetRawValue() to allow developers to override the default formatting behavior by either subclassing Header or by calling header.SetRawValue(). (issue #546)
* Switched MimeKit for Android and iOS over to using Portable.BouncyCastle.
* Added MimeTypes.Register() to allow developers to register their own mime-type mappings to file extensions.
